Tesla Powerwall is a product line of rechargeable lithium-ion home energy storage manufactured by Tesla Energy, a division of Tesla. Its purpose is to store backup power, allow the owner to use an alternative source of energy during peak hours, or otherwise for self-consumption.
Consumer impact summary
User freedom
- Requires company app: To have full use of functionality and features, the customer must download the Tesla application.
- Always online: The product itself does not require internet connectivity per se, but certain features will not be available. More notably, it is stated in the limited warranty agreement that failure to register and connect to the internet will greatly decrease the duration of the warranty.[1] This effectively "encourages" the customer to always be connected so that Tesla Energy can remotely push firmware updates.
- Arbitration: Agreement includes usage of mandatory arbitration.[2]
User privacy
The product must be registered to a Tesla account.[3]
Market control
Since Tesla Energy does not provide official numbers, it is difficult to determine the Powerwall's popularity in the home energy storage market.
Incidents
Powerwall 2 recall and lawsuit (2025)
On 16 September 2025, the Australia Competition and Consumer Commission published a notice that Tesla was recalling affected Powerwall 2 units due to "certain lithium-ion battery cells from a third-party supplier in a subset of Powerwall 2 systems that may fail and overheat".[4][5]
A recall was issued nearly two months later, on 13 November 2025, by the United States Consumer Product Safety Commission due to the same concerns.[6]
In both cases, Tesla had also pushed a remote update to affected Powerwall 2 owners that limited or drained the batteries and disabled its ability to recharge.[7]
A class action lawsuit was filed 26 November 2025 in Florida by Arthur Brown, an owner of a Tesla Powerwall 2 unit.[8] On 10 February 2026, Tesla filed a motion to compel arbitration, with the judge both granting in part and denying in part the motion on 30 April 2026.[9] The lawsuit was stayed pending arbitration and administratively closed.[9] On 8 October 2026, the lawsuit was voluntarily dismissed.[10]
